An undisturbed sheet of fallen snow has the unique property of offering to the public an omnipresent notepad. What would you suppose might be on a person's mind that they might want to share with whoever will pass by in future? If you thought of some crude, self-important, or derogatory message, get out more and go for a walk... most of the time what was written in the snow had a "<3" somewhere in it. Those I remember best: "YINZ ARE MY HEROES", "youtube Zeitgeist Addendum", "<3 is all u need", "FATE / LUCK". (Now I did walk around a lot, but I didn't see the whole city, so do share what you saw!)

I was also quite amused on saturday morning to see a guy on cross-country skies zooming up forbes.

The answer is of course "machine translation", but I was thinking "markov... trains!" Drawing challenge!

"deMorgan's Lawn"

go!

(i cannot draw recognizably, so I will give a text description instead; using it is smiled upon: a house with street address zero with its front lawn extending infinitely in two directions, an old man waving a cane, and a signpost saying "please do not walk on the irrationals".)

edit: argh, just like when i was doing my real analysis homework i confused demorgan's with l'hopital's. the signpost should say "please do not walk on the complement of the sidewalk".

for the first time in a few months, i have working headphones (with much thanks to [info]j4cbo ). not having headphones means i haven't been able to properly listen to music regularly - currently idling and receiving aural stimulation, and I can feel my energy levels increasing faster than is perhaps healthy. combined with housecleaning, soon i will be running on close to full charge again, and hopefully even levelled out.

poll: when somebody owes (or offers) you a generic favour, what sort of thing would you most appreciate?

for example, i would much prefer being bought a meal than being paid as much money as the meal would cost, since the former gives the pleasure of good effortless food without the guilt of "i should cook for myself to save money" (aside: certain clever companies use free food (instead of higher paychecks) as a subliminal "you really love working for us" mechanism). other gifts i can think of off the top of my head include electronic gizmos (generally to be avoided, since they are soon taken for granted and thus cease giving pleasure), backrubs (good, but small in comparison), other material possessions (i enjoy making chainmaille more than possessing it, really), other immaterial services (good, but hard to think of?).

unfavorably comparable to the clutter in my house that seems to take a lot of ghanners's cycles is the clutter in my head that seems to have come about as a result of countless instances of "i'll think about this later" over the past semester. i have been feeling better as i do more practical things (like cleaning) but i can't tell if it's actually cleaning mind-clutter or just laying new carpeting over anything.

i try to squeeze as much juice out of life as possible but sometimes i feel like i'm doing a miserable job at it. (perhaps a different sort of *juice* *squeezing* is in order!)

I am not sure how the phrase came into my head but there were before this post no google hits for "cardinals of that magnitude". so, I think this is okay for a drawing challenge - anything that could be captioned with that would please me greatly.

my winter break was spent first in virginia (friends), then in north carolina (immediate family), then in southern california (register and memory family), and finally back in north carolina again. the california part was filled with wandering around looking at stuff and having family members pay for me to eat extremely swanky food. it was also filled with the frustration of spending several weeks around my family, which causes me to clamshell away.

i'm putting the sad part of this post first so it ends on an amusing note. )

some snippets follow. )

one of the things that really bothered me about vacation is not being around people who think like CS majors. it is good to be back.

our house is kept at around 65F for gas bill reasons. so, if I'm stationary in the house for any appreciable amount of time, my fingers and toes start to chill and stiffen up. when I went to shower today, my hands were deeply cold, though not to the point of being numb. I tested the shower water before stepping in and found it to be standard acceptable shower water temperature - imagine my surprise when I was deluged with water slightly below room temperature. of course my hands were used to being cold, and it took until they felt like they were being burned until the water was actually adequate.

hooray for winter. may none of you repeat my mistake.

you know how when kids draw pictures of houses, there's always a blank gap between where the horizon is and where the sky gets coloured in with blue? I used to do that, at least, and one day in elementary school when I was drawing like that, my teacher took me outside, pointed at the sky, and asked me how much of it was blue. from then on my little-kid landscape drawings always had all of the sky done in as blue instead of just the top portion.

I drove to chapel hill from richmond today, which is about two hours southwest on I-85, which is a phenomenally pleasant highway: two lanes, lined with trees of dark orange and green, and compatible with cruise control most of the way. When driving down it, the sky looked like one of those little-kid drawings: above the trees, a narrow band of blankness (empty sky, red-orange) below a thick layer of colour (clouds, purple and pink). One particular moment, driving slightly uphill in the shade, I noticed the guard rail off to the left at the top glowed bright red, and as I crested the hill, the blindingly red-orange sun came out from behind the trees on the side, right below the bottom of the clouds. Shortly afterwards, it went to hide behind the trees again, and the rest of the drive was marked by watching the periodic streaks of fire in front of the clouds and the darkening bands of sky.

my new year's resolution is to get better at the practical things that keep my mental health up to spec. I hope to have more energy to give to everybody in the coming year.

Hack me again and I can't believe it's true
Smashing the abstraction was not my intention to do
Neither did you

GDB such an outcome to the unnecessary ending
I wish I could revert my commits and erase all my breaks
With you

I wanted to say you shouldn't buffer this way
I wanted to say I hope I can Make it away

Branch me again and I will forget the truth
Acking your revision was something I neglected to do
Even for you

If you feel rage to strike me with reverts
I will be standing right here updating without fear
For you

I wanted to say you shouldn't buffer this way
I wanted to say I hope I can Make it away

i saw the sun rise in the west today. not much different from seeing it rise in the east, but still an experience.

i am in los angeles for five or six days now. even from a few hundred up, the place is city lights all the way out to the horizon. it occurred to me when observing this the different natures of various cities - how i could never live in a place that big. it has more personality than new york, though. we ate pho at a hole-in-the-wall vietnamese place a block from the ocean in the city i was born in (venice, which is like venice, but with less boats). it was one of the better dinners i'd had in a while, and not entirely due to food quality.

ugh.

you may have noticed i have not posted in a while. this is because i have not done any thinking in a correspondingly long while, which in turn is because i have had no energy to devote to doing so in as long. the semester is over, mostly, and now i am going to do the run-down of classes postmortem thing that seems to be popular among the little chiblens these days.

15-381 Artificial Intelligence, a.k.a. "algo": taught by luis von ahn (there is no von Ahn, only vonAhnism) and manuela veloso, this fulfillment of my applications requirement felt like a sequel to 15-451 (algo); hence why i repeatedly - mostly unintentionally, too - referred to it as "i have algo homework to do this week". i, like most of the classmates in my immediate social circle, ceased going to lectures for the most part about halfway through the semester. of particular note was one time towards the end that i decided to go on a whim, and discovered to my dismay that nobody else I knew at all was there, and also the slides being presented (game theory) were exactly the same slides that I saw a year ago in 15-396 science of the web. as for the final exam, i walked out feeling i'd done about as expected, and appear to have gotten a B finally. (went to algo none of the time, got a C; went to AI half the time, got a B; ...)

36-217 Probability Theory and Random Processes, a.k.a. p_t *ptrp = &p;: the much-loathed "PTRP" of legend! i went through the final exam feeling like i was managing to get all the flashes of intuition the problems needed me to get, surprisingly, and walked out feeling like i'd really earned whatever was on the higher end of the range i was shooting for, which at the time was "D or C". My final grade turns out to be a B. shock and relief.

15-317 Constructive Logic: one cut, two cut, red cut, green cut. blazed through the final exam, an appropriate ending to my performance on the homeworks steadily increasing from "lucky to get half the homework done" to "nearly all the points all the time" through the semester. my final total turned out to be 0.4% above the cutoff for an A. phew again! i generally feel fairly wonderful about how that class went in terms of how i dragged and hiked myself through it and in terms of how much was learned. (william: be proud of yourself! running a class that works that well takes a lot of effort and skill.)

85-390 Human Memory: after consulting with mark, i took a W at the start of the last week of classes. this was one of the better decisions i've made; i think without it my showings in everything else would be much poorer.

15-213 TAing: the semester ended well, i think. i ran my question on the final exam about bailout gotos, which worked by means of being the "reverse this assembly into C" question. it was intended to be an easy question, and so it was, judging by the scores; it was also supposed to teach the students something new, which i think it succeeded at. next semester i am taing 213 again, and going to fix the rest of tshlab so it is all consistent and good at the same time.

15-412 Operating Systems Practicum: if this is a postmortem, then 412 is cutting itself out of the coffin and wielding a shovel. it was even before exam week started that i'd gotten enough feedback from LKML to finish everything up for the last time, but never found the time to actually do it. exam week came and went, and eventually, with three half-days of work, I finished and submitted it today (for the third time in a month). too late, of course, for the academia monster: eckhardt assigned me an incomplete (like I asked) for final grades, and I have to deal with retying all the loose ends so I can end up with a real grade. Probably going to be an A, as i do like how my project turned out, but until it's over it's still an obligation.  
 
overall, i feel like I got away from that semester very, very luckily unscathed. through exam week, the fluctuations i had in focus, energy level, and pleasantness to be around were a complete mess; during the semester, it was not as bad, but still barely sufficient for me to keep up with my work, and certainly not clean enough for me to be cheery all the time. my aim for next semester is to at any time be able to walk into the cluster and smile at everybody - among other things, to do this i will need to take many more weekends to do nothing but destress than i did this semester. i will also need to start homeworks earlier (ha ha), appreciate walks, do pushups (you know who you are), go climbing (you know who you are), and cook for myself more.

for now, i am attempting to use winter break to pack up everything, drain the remaining inertia from stumbling blindly along for four months, and reset completely. i expect i will need all of break for this. i am at my auxiliary home, in north carolina, and i spent a day today doing nothing. i had a mexican chocolate gelato after dinner; it had ancho chili in it. it was the best thing.

in this file one can find the mysterious function static int userspace_tramp(void *stack)

today I would like to see a depiction of this alleged Userspace Tramp, or perhaps alternatively the IRQ Wench. Also acceptable would be a Networking Harlot or a Filesystem Escort. (bonus points for an interaction with the thread-id hamster)

Katie, who is one of the c2.0 people, has drawn a grocery isle ) for me, at prompting of [info]sageofminerva. I wondered what the huge bird was all about, and perhaps if it was a lot closer to the camera than the island was when the picture was taken. As it turns out, it's actually a giant eagle.

The previous two days have seemed like much longer. I drew the short end of some stick and had my two hardest finals on the first two days of exam week. When I take exams, something in me takes most of the energy that I have, which was meant to be spread across the whole day, and uses it for making my brain go during the test. This is good, because - for example - during the PTRP final I made a lot of the key insights that the problems wanted me to make that I wouldn't have made on any homework. On the other hand, it eats the rest of my day: I end up in a very fragile mood afterwards, and rarely ever do anything useful (studying on monday for the PTRP on tuesday after the AI final earlier did not in fact happen until 2200 or so).

I have started doing a clever thing. A week or so ago, I went to the bookstore and bought pads of small sticky notes. Once each day, whenever I see something lying around our house that should have been cleaned up, I put a sticky note on it. The number of stickies on any given object will then indicate the number of days it's been sitting about without being taken care of. This is a sort of silent gesture that I really like - funny but also useful. Mostly it is for making fun of my messy houfemates, but also I got a few strange looks when I started doing this, and also I think I've been sticking fewer things recently.

Read-write locks -can- still deadlock even if you're taking them only in read mode.

It snowed today. It snowed all across the east coast, apparently. Pittsburgh added its own typical flavour to the weather, of course, and there wasn't an appreciable amount of snow on the ground. Instead, you should go outside sometime soon and appreciate something else in life - it will make you happier, and also encourage the snow to show up again.

Sometimes one just has to put enough effort into something before it can click and start working, though until then it may seem fruitless. The snow will accumulate eventually, I am sure. (Here's hoping it's before I leave pittsburgh!)

the most interesting things are discovered in the small hours of the morning, but they are always accompanied by unpleasant circumstances.

yesterday afternoon was spent on several frustrated attempts to grok the language in which the final clogic assignment was to be implemented. the actual productivity that happened around then actually had a lot more to do with 412. after midnight or so, I actually got about half the points' worth of clogic done, amidst complaints that whoever came up with the syntax of the lollipop operator ("-o" in lollibot, the language) was intentionally trying for the most alien symbolism possible, and that there should be some standard for which directions inferences go when written down and that trees do in fact always have their roots at the top and grow down. this finished around 0400

finished the last ptrp assignment, by which i mean, 45% of it, and handed it in. this was at around 0800 or so - slightly before which I discovered that Tazza has freshly baked pastries just after opening time, and also various notions of life being completely wonderful (possibly related!), and just after which I paid a visit to jboning and company in the 5207 cluster. thereafter I returned to the Mystery Science Cluster 3000, attempted to parse the rest of the constructive logic, but realized it was not going to happen. I then - at 0930 - scrawled a note on the whiteboard saying "Under no circumstances should I be allowed to be asleep after 1130" and lay down on a beanbag.

After finishing the third quarter of clogic's points starting at 1128 I went to clogic lecture and proceeded to spend most of the time there doing the final problem, which was actually a really cool and interesting thought exercise.

213 had a review session in place of lecture, which I went to and multitasked reviewing for the students and teaching myself how to run proxylab interviews. Immediately afterwards I simultaneously conducted a proxy interview (just outside the room I'd intended, since it was used for a surprise kernel interview at the same time) and issued an email announcing that my office hours, conveniently at the exact same time, had moved to my proxy interview location. I also offered extended office hours as an apology for the relocation, and the last dude from office hours has just departed with the best help I was able to give him in my state; i.e., not much.

I am however now past everything that I have on my todo list, besides 412 project and exams. If only I were running on enough sleep to be able to appreciate it.

congratulations to everybody who did more impressive things than me for this month! your dedication has been admirable.

thinking of something to say every day was an interesting exercise. some days are just not cut out for it though. however, I estimate that I'm likely to more often find things to say than before.

also it appears I posted pictures exactly 2/3 of the time )

I succeeded at making this thanksgiving break relaxing despite the prospect of spending the whole time around my family. today I made a fatal mistake: not eating at all until arriving again in pittsburgh, at which point I hit up kivers han and subsequently went to the cluster and promptly crashed very hard. two or more meals a day is generally advised.
